Mnemonic
Function
1
VDD1
Power Supply (Logic Side).
2, 8
GND1
Ground (Logic Side).
3
R×D
Receiver Output Data. This output is high when (A – B) > 200 mV, and low when (A – B) < –200 mV.
The output is three-stated when the receiver is disabled, that is, when RE is driven high.
4
RE
Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver, and driving
it high disables the receiver.
5
RTS
Request to Send Input. Driving this input high enables the driver, and driving it low disables the driver.
6
TxD
Transmit Data Input. Data to be transmitted by the driver is applied to this input.
7
PV
Power_Valid. Used during power-up and power-down. See the Applications Information section.
9, 15
GND2
Ground (Bus Side).
10
DE
Driver Enable Status Output. This output signals the driver enable or disable status to other devices on
the bus. DE is high when the driver is enabled and low when the driver is disabled.
11, 14
NC
No Connect.
12
A
Noninverting Driver Output/Receiver Input. When the driver is disabled, or when VDD1 or VDD2 is powered
down, Pin A is put into a high impedance state to avoid overloading the bus.
13
B
Inverting Driver Output/Receiver Input. When the driver is disabled, or when VDD1 or VDD2 is powered
down, Pin B is put into a high impedance state to avoid overloading the bus.
16
VDD2
Power Supply (Bus Side).
